Construction method of operation platform for construction in deep and thick peat soil area

Abstract

The invention provides a construction method of an operation platform for construction in a deep and thick peat soil area. The construction method comprises the following steps that D, within the range of a machine arm of an excavation machine, a roadbed trough is excavated; E, geotechnical cloth is laid on the bottom of the roadbed trough; F, sea sand is filled back into the roadbed trough, and aprimary platform is formed; G, the excavation machine is moved to the primary platform obtained in the former step; and H, the steps from D to G are repeated until all primary platforms in the construction area are completed, wherein in the step H, every time after the primary platform of a certain distance length is completed, the sea sand is filled back above the primary platforms and compacted, and the operation platform for construction is formed. According to the construction method, permeable performance and reinforced performance of sea sand resources and the geotechnical cloth are fully utilized, the bearing ability of the base is enhanced, it is ensured that equipment comes in and out of a site and operates normally, the construction error of the mechanical equipment due to uneven settlement is avoided, and the reliable guarantee is provided for construction of follow-up foundation treatment.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a construction operation platform in a deep peat soil area. Background technique [0002] In order to reduce damage to land resources and demolition work, most of the expressway routes are selected from swampy land, lagoon areas, and areas with few buildings. Most of these areas are deep peat land. Peat land has the characteristics of large natural water content, large natural pore ratio, high compressibility, and large permeability coefficient. When used as a foundation, there are problems such as insufficient bearing capacity and uneven settlement, which will cause large-scale Construction machinery cannot enter the site, which affects the construction operation of foundation treatment. A construction operation platform must be built before foundation treatment to meet the requirements for large-scale construction machinery to enter and l...

Problems solved by technology

Most of these areas are deep peat land. Peat land has the characteristics of large natural water content, large natural pore ratio, high compressibility, and large permeability coefficient. When used as a foundation, there are problems such as insufficient bearing capacity and uneven settlement, which will cause large-scale Construction machinery cannot enter the site, which will affect the construction operation of foundation treatment. A construction operation platform must be built before foundation treatment to meet the requirements of large-scale construction machinery entering and leaving the site and normal operation.
